All these options are enabled by default. Changes take effect immediately (no viewer restart required) so you can easily experiment with them.

The “Timewarp waits” option shouldn’t really be made visible to the user, but in my testing I found that it seemed to help to be able to turn it off if rendering at significantly less than the frame rate the DK2 is set at. The variability of the frame-to-frame timing in Second Life may well be why.

The optimum settings depend on what frame rate you’re achieving and your personal preferences and sensitivities to different display behaviour: if you’re achieving the ideal of 75Hz including while turning your head then the default of all options enabled is best; otherwise you will probably want to try disabling one or more, consider configuring your Rift display to 60Hz, and possibly try enabling triple buffering in your display driver.

Other changes this version:

Updated GPU table. This now includes NIVIDIA GTX 970 and 980 graphics cards.

Please note that this alpha still does not work with direct mode, and Advanced Lighting Model needs to be turned on. It is built using the 0.4.3 Rift SDK and if you haven’t done so already you should update to the 0.4.3 Oculus runtime.
